APPARATUS FOR DRYING OILS.

Specification of Letters Patent.

Patented time an, 1915.

Application filed September 30, 1914. Serial No. 864,331.

To ail whom it may concern Be it known that I, a citizen of the United States, residingat Palo- Alto, in the county of Santa Clara and State of California, have invented new and useful improvements in Apparatus for Drying Gila, of which the following is a specification.

This invention relates to an apparatus for neutralizing, clarifying and drying oils, particularly oils made from California asphalt base, crude oils for lubrication or other uses, wherein the hydrocarbon oil is first treated-in an agitator by the action of an acid to remove the tarry constituents, then subjected; to a process whereby the acid is neutralized by remove the'allrali, and the neutralized oil finally relieved of its watery particles or all moisture adherent to it after it has been so washed.

The primary object of my invention is to rovide a simple type of apparatus by which the operation of drying theoils may he car ried out in a rapid, efficient and economical The invention consists of the features of construction, combination and arrangement ofparts lierein fullydescrihed and claimed, reference beingih'ad to the accompanying air supplying and compartments. In showngas provided r mary and secondary compartments 3,-"each having bottom closed drain outlet. 5 for theremoval-oi any aponaceous or other residue left remaining .f'ter the oil is neutralized. In the bottom of each of the saidcompartmentsfi and steam lVILLiAM P. Bnunrno,

If desired, the tank or vat compartments may be steam jacketed at the ing means omployed Within the tank or vat compartments.

The oil to be treated is first conveyed from the acid agitator to the compartment in which it is subjected to a preliminary process of neutralization, and thence trans- 'ferred from the compartment 2-to the c0mpertinent 3, if desired, for a further orfinal step in the process of neutralization and ried out in either compartment, as desired. A discharge pipe 10 for the neutralized oil is provided with branches communicating with a basine of the vet compartments and leads from the tank to a suitable pump 11,

I whereby the neutralized oil is drawn from the vat andsupplied to the clarifying and drying portion of the apparatus for treatment. it will, of course, be understood that the oil treated in thevat is not onlyneubottom or other heat-- washing, or the entire process may he cartraliz'ed but clarified to a determined degree.

in the course of further treatment in the clarifying and drying part of the apparatus, above referred to, the oil is further clarified by oxidation and moisture driven therefrom.

The neutralized and washed oil drawn by the pump 11 from the vat through the suction or discharge pipe 10, is forced by the pump through a delivery pipe 12 into an elevated heating-chamber or casing 13, wherein a desired temperature of tained during the clarifying and drying treatment; in thischamber or casing-13 is heating coil 1.4 inlet-.15 designed to communicate with any suitable source of steam supply and a valve outlet 16. The casing 13 is arranged at any suitable elevation within a tower or stand ancllcommunicates at its top and and lower sections thereof. 'ln'thetop'oi said casing is a receiving trough 18 which communicates with and receives the oil'therefrom, and which is provided in its bott in vilill an elongated contracted outlet 19 overlying the coil 1- so as to cause the oil to flow downward over-the1 coilin direct contact thereitheud ebeheated to an e icient egreepipe .17

is provided. with a hood to prevent the 5 entrance of snow or rain water, while permitting of the outflow of air and the H1015? ture from the oil carried oii thereby.

The heated oil passes by gravity down through the lower section of the stand pipe 17 which is arranged to discharge the oil into a combined receiving vessel and ventilator 21 having a conical upper portion and a cylindrical lower portion,

' the latter communicating with the receiving 220i a purified oil receiving tank 23, which also has a discharge portion or chamber '24-, said chambers being separated except at their bottom portions by a partitio' 25, terminating'sufl 2o fi'oientlyabove the bottomof theta-11k to provide" a" constricted new: passages til'ator and into said "stand pipe; and: thence 25 topassupward through the standpipe and easing 131'and' to 'fina'lly"'pas s' outwardly through the outlet 20. it will beunder'stood that this air is heated on its upward passage and rises-and finally discharges and hence induces" acirculation in the stand pipe, wherebyfresh air is drawn into the stand jpem ough; the ventilator for upward movefiienti'and discharge, as before; de-

The pipe 28 depends into the chamber 24' to a point just above the level of the passage between the chambers 22 and 24: formed by the baflie' or partition 25, which thus provides: a normally sealed trap between said chambers which prevents the passageofthe air from the fan 23, when the latter 15 111 action,
